At age eleven, the boy observed Santa Claus arriving and climbing the through the balcony on the second floor.
As the old fat guy came in the kid shot him point blank in the heart with his dad's .44 magnum revolver. Got him square on the heart and catapulted him backwards into reverse flight to the sidewalk. Just as this happened the father arrived and saw the fresh corpse splatter on the cement still gushing blood all over the concrete ground.
He ran into his home to find the child with the gun still smoking as he uttered:
---Thank you daddy for not making me believe in Santa Claus the same way some parents fool their kids.---
The man replied:
---Thank you son for being so smart and not believe in bullshit and protecting your siblings while I'm not home.---
Meanwhile the police and the emergency services worked at containing the crowd and lifting the body away. Some bystanders wept for the dead one. A tiny girl moaned:---Poor Santa, he's dead.---
Once the investigation concluded it was revealed that the man was a murderous burglar with a lengthy rap sheet, and the boy in the newsclip told the interviewer how dad trained him to get a body shot to reduce the risk of missing.
After the news they had a Christmas music special.
